'''Setup | '''Setup''' | ||
I filled a tube with the Euglena medium (capacity: 15ml) and added about ten drops of Euglenas. To make the light colorful I cut out three stripes of transparent paper and wrapped them around the tube. I chose the fundamental colors yellow, red and blue. | |||
As a comparison I also prepared a tube without any paper. | As a comparison I also prepared a tube without any paper. | ||
To not move the tubes when I put off the paper, I put them in my Euglena Workstation to keep them safe. So I can easily remove the paper without mixing the concentrations accidentally. | To not move the tubes when I put off the paper, I put them in my Euglena Workstation to keep them safe.

I guess that the concentration will be very low behind the red and blue paper. As I read during my researches, Euglenas don’t react to red light. Blue is a pretty dark color and I think it won’t attract the organisms much. The yellow paper seems to be the most transparent, so my assumption is that the concentration will be the highest there. | |||

Note: I will start this experiment as soon as the Euglena medium is greenish enough to recognize the visual difference. This experiment is supposed to be repeated with different colors. | Note: I will start this experiment as soon as the Euglena medium is greenish enough to recognize the visual difference.
